CREAM BREAKER AND MELTER.

No. arance.

To all whom it may concern.'

Be it known that I, JOHN WERNER- a citi- States, and resident ofRochester, in the county of Monroe and State of New York, have inventedcertain new and useful Improvements in Cream Breakers and Melters, ofwhich the following is a specification.

This invention relates to cream breakers and melters, and consists inthe construction and arrangement of the apparatus herein described andclaimed.

The object of theinvention is to provide an eilicient apparatus for thepurposes hereinafter set forth. l

In the drawings: Figure 1 is a top plan view; and Fig. 2 is a section onthe line 2 2 of Fig. 1.

The melter has an outer kettle 1, hemis herical in shape, and supportedat a suita` le height from the iioor on legs 2. A smaller hemisphericalkettle 3 rests within the kettle 1, and is bolted thereto through aflange 4. Iacking is placed in the joint to make it steam-tight. In thespace between the kettles 1 and 3 is a pipe coil 5.v Steam is admittedto said coil at 6, and escapes from its upper end, condensing more or-less rapidly upon the outer surfaceof the kettle 3, and the innersurface ofthe kettle 1. When the water thus formed rises to the top ofthe kettles, it may overow through a pi e 7. This construction istherefore a jackete kettle. The steam fin the coil 5 maintains the waterat its own temperature, and the cream candy placed in the inner kettleis melted by contact with the sides thereof. The melted cream may bedrawn 0E through a pipe 8, located near the center of the bottom of thekettles, and closed at its outer end by a valve 9, such as amolasses-gate.

The mechanism for breaking up large pieces of hardened or unmelted creamcomprises a vertical shaft 10in the center of the inner kettle 3, onwhich is'iixed aseries of collars, each. :having o positely extendinghorizontal blades 11 and 12 The shaft 10 is revolubly supported in abearing 13 at the bottom, and in a bearin in a frame 14 at the' tcp. Onits upper en is a bevel-gear'15, a apted to mesh with a gear 16. Thegear 16 :lsxed to fa horizontal driven shaft'17, in bearings 18 an 19,and usually carrying a driving pulley as shown.

The shaft 10 is rotated in the direction in- Speccatiion of LettersPatent. Application led November 30, 1907.

dicated by the arrow in Fig. 1. The blades 11 are so formed that theypresent a concave operating edge toward the direction of rotatlon, andthe blades 12 are so formed that they present a convex operating edgethereto.

such a position that each pair of the blades in advance of the pairbeneath, (Fig. 1), and thus they may be called s irally-ste'pped. Thefront edge of each b ade, which is toward the direction of rotation, isbeveled downward and backward from the top (see the blades 12, Fig. 2),so that as it comes in contact with the lumps of cream, the latter arenot only broken up, but are also wedged downwardly toward the bottom ofthe kettle 3. To insure a finer division ofthe lumps of cream, a seriesof stops or abutments is placed in the kettle 3, and the blades 11 and12 pass between the stops once during each revolution of the shaft 10,.thus being cleared of large pieces which may adhere to them, anddividing said pieces into finer particles. The stops or abutments in thepresent instance are iiat bars 20, each of which lies in a `horizontalplane between the paths of rotation of two of the pairs of blades 11 and12. The outer ends of the bars 20 are bolted to suitable lugs 21 on theinside of the kettle 3, and the inner ends are formed as collars 22,which lie between the collars, and fit loosely around the shaft 10.' Thebars 20 are not in alinement vertically, but each is somewhat in advanceof the one next above it (Fig. 1). Said bars are thus relativelyadvanced or s irally s'te ed in a direction opposite to that of thehllades 11 and12. No more than one of said blades, therefore, can passbetween two of the bars 20 at the same time; one blade is completelyclear of the two bars between which it passes when the next bladebeneath it approaches the bars lying. adjacent to its plane of rotation.This sp1- ral arrangement prevents the eXcesslve strain on the drivingmechanism which would occur if all the bars v20 and blades 1,1 and 12were to pass each other at the same instant. The lumps of cream are thusbroken up into comparatively small sizes, without requiring any greatamount of power to operate the machine, and without undue strain uponany part. The effect of the concave knives 11 is to tend to move the lums of cream inward toward the center of t e kettle, and the convex knives12 tend to The collars are set upon the shaft 10 in move the lumpsoutward, so that the lumps receive thorough treatment, andthe mass isthoroughly mixed:

What I claim is l. The combination of a melting kettle, a rotary shafttherein having oppositely di- .rected spirallystepped blades thereon,and

stepped stationary stops between whlch t e 4 blades ass.

3. T e combination of a melting kettle, a

rotary shaft therein having two oppositely directed series ofspirally-stepped blades thereon, one series having concave operatingedges and the other series having convex op-- erating edges, and aseries of stationary stops between which the blades pass and which are-spirally-stepped opposite y to the blades.

4. The combination of a melting kettle, a rotar shaft therein having twoseries of s iral -arranged and oppositely directed b ades thereon, eachpair of blades being slightly in advance of the next pair, and a seriesof spirally-arranged stationary stops beass and in which one. kettle, a

tween which the blades each stop is in advance o the next 5. Thecombination of, a melting Y, rota shaft therein having two series of sira y-arranged and oppositely directed b ades thereon, each pair ofblades being slightly in advance of the next pair, one series havingconcave operating edges and the other series having convex operatingedges, and tionary stops between which the blades pass and in whi h eachstop is in advance of the next one.

6. The combination of amelting kettle, a

rotary shaft therein having two opposltely` directed series ofspirally-arranged blades thereon, one series having concave operatingedges and the other` series having convex opa series ofspirally-arranged staerating edges, and a series of stationary stopsbetween which the blades pass.

7. The combinationof a melting kettle, a rotary shaftvthevrein havingtwo oppositely directed series of spirally-arranged blades thereon, oneseries having concave operating edges and the other series having convexoperating edges, and a series of stationary stepped stops between whichthe blades pass.

8. The combination of a melting kettle, a rotaryshaft therein having twooppositely directed series of spirally-stepped blades thereon, oneseries being long and having concave operating edges and the otherseries being short and having convex operating edges, collars on theshaft, and a series of stops between w hich the blades pass extendingfrom the collars to the periphery of the kettle.

l0. The combination of a melting kettle, a
